DONALD C. MORGAN, F INDIANAPOLIS,

INDIANA, ASSIGNOR TO AIKERICAN SANITARY LOCK C0., OF INDIANAPOLIS, INDIANA, A CORPORATION OF INDIANA.

COIN-CONTROLLED LOCK.

Application filed November 5, 1921.

To all whom it may concern:

Be it known that I DONALD C. MORGAN,

a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Coin-Controlled Look, of which the following is a specification.

The object of my invention is to produce a compact, cheaply manufactured, and efficient coin controlled look, more especially designed for toilet locks, of such character that subsequent to the insertion of the coin and prior to the entry of the customer into the enclosure, the latch may be, if desired, repeatedly manipulated but of such character that, as soon as thedoor has been closed, following the opening thereof, the latch is no longer operable from the exterior until the door has been opened from the inside and reclosed. I

The accompanying drawings illustrate my invention. Fig. 1 is a front elevation; Fig. 2 a side elevation; Fig. 3 a horizontal section on line 3-3 of Fig. 1; Fig. 4: a horizontal section on line 4-4 of Fig. 1; Fig. 5 a fragmentary vertical section on line 5-5 of Fig. 3; Fig. 6 a fragmentary vertical sectlon on line 66 of Fig. 3; Fig. 7 a view similar to Fig. 5 with the parts in the positions 30 which they occupy at the end of the initial opening movement of the external knob, and Fig. 8 a fragmentary vertical section on line 88 of Fig. 4.

In the drawings, 10 indicates a suitable enclosing casing provided with a coin-receiving opening 11 and sliding guard plate 12 therefor, said guard plate being L-shaped in cross-section so as to have a portion 12 blocking a sight opening 13 in the casing and displaying the words Vacant or Occupied depending upon the position of the uard plate.

Ained with the opening 11 is a C0111- receivin guide 15 adapted to receive, hold and guide a coin 16. At 17 the guide 15 is notched to receive a rock shaft 18 laterally notched at 19 and so arranged that, when in the position shown in Fig. 6 it will serve to hold coin 16 against further movement through the guide, and when in the position shown in Fig. 8 will release the coin and permit it to travel onward. The rear wall of coin-guide 15 is provided with a curved cam slot 20 which substantially conforms to the curvature of the adjacent portion of Serial No. 512,987.

the coin 16 when the same is in the restrained position shown in Fig. 6.

lournaled in casing 10 is a shaft 21 carrying the external knob 22. Secured to shaft 21 is an arm 23 provided with a cam surface 24 which acts upon a shoulder 25 carried by a latch bolt 26. Pivoted to finger 23 is a stop finger 27 which normally lies in a notch 28 in frame bar 28 so as to come into engagement with a shoulder 29 and stop further movement of shaft 21 just before pin 30 carried by finger 27, comes into engagement with the lower edge of the cam slot 20, the arrangement being such, however, that, if a coin 16 is in position as shown in Fig. 6, finger 30, engaging the edge of the coin will lift finger 27 out of notch 28 and 13611113) opening movement of the external As the shaft 21 is advanced (a coin 16 being in place) it forwards a lever which is journaled on shaft 21 and connected thereto by pin and slot connection 36 which per. mits a considerable relative angular movement between the shaft 21 and lever 35. Lever 35 is provided with a finger 37 which engages a shoulder 38 (dotted lines Fig. 1) and moves the guard slide 12, against the action of spring 39, from its normal or vacant position to the occupied position as shown in Figs. 7 and 8. Lever 35 also, through the medium of the cam sur face 40, engages arm 41 on rock shaft 18 and shifts said rock shaft from the normal position, shown in Fig. 6, against the action of spring 42 (dotted lines Fig. 6) to the position shown in Fig. 8, thereby releasing the coin 16 and permitting it to drop in the lower part of the casing.

Normally a locking pawl 44 is held against the curved end 15 of lever 35 by spring 46 and when lever 35 is carried to its farthest position in the opening direction, the locking pawl 44L will drop in behind shoulder 47 of lever 35 so as to hold said lever temporarily in the position shown in Fig 7, at the same time serving to hold rock shaft 18 in the position shown in Fig. 8. The movement of lever 35, through the medium of link 48 and arm 49 serves to operate a counter 50 which will show the number of coins which have passed into the apparatus beyond the rock shaft 18.

Because of the pin and slot connection 36 between shaft 21 and lever 35, and because of the locking action of pawl 1 1, the shaft 21 is left free to be manipulated back and forth through a considerable angle so as to manipulate latch bolt 26.

Also, secured to shaft 21 so as to partake of all of its angular movement, is a finger 52 to which is attached a spring 52 serving to normally move the shaft to initial position. This finger 52, at its upper end, initially lies beneath a finger 53 carried by a pivoted arm 54 normally urged to the position shown in dotted lines in Fig. 8 by spring 55, but when an initial opening movement of shaft 21 is made, after the insertion of coin 16, the upper end of finger 52 moves from beneath finger 53 so that, on a return movement of shaft 21, the finger 53 drops down, to the position shown in dotted lines in Fig. 8, and prevents return of shaft 21 to its full normal. or initial position, but, nevertheless, permits free manipulation of the shaft 21 in the opening direction so that the latch 26 may be repeatedly retracted although the coin 16 has been released by the first retracting action and has passed beyond the control of the customer.

As soon, however, as the external knob is released and the door is closed, after having been opened, the inward projection of latch 26, due to its co-action with the strike on the door jamb, brings a shoulder 58 into engagement with portion 59 of arm 54 and retracts finger from in front of finger so that spring 52 will move shaft 21 to its initial position thereby permitting the upper end of finger 52 to pass under finger 53 (as shown in dotted lines in Fig. 6), thus permitting the locking pawl 27 to drop into notch 28 and thus lock shaft 21 against further manipulation until the insertion of another coin.

Parts 35, 4: 1 and 12, however, remain in the projected position as indicated in Fig. 7, until the customer leaves the compartment, at which time manipulation of the internal knob 60 and the shaft 61, to which it is attached, against the action of spring 62, causes arm 63 to engage shoulder 64 on the latch bolt 26 so as to retract. At the same time an arm 65 on shaft 61 is brought into engagement with the locking pawl 14- so as to retract said pawl from shoulder 17 and thus permit lever 35 and rock shaft 18 to be returned to normal, slide 12 being simultaneously returned to normal by spring 39. So long as finger 53 is in position to restrain full returning movement of shaft 21, pin 30 remains in the cam slot 20 to asufficient extent to keep finger 27 out of notch 28 although coin 16 has been released and passed onward, but whenever finger 53 is retracted to permit full return of shaft 21 to normal, the finger 27 will drop down into notch 28.

In order that a caretaker may enter the compartment without the use of a coin. or

control check, and without manipulating counter 50, I provide a special key-controlled. lock 70, the barrel of which is provided with a finger 71 adapted to engage a shoulder 72 carried by latch bolt 26. Finger 71 is connected by alink 73 and arm 74 with a special counter 75 so that the number of entries by the caretaker may be known and the owners thus determine whether the caretaker is performing his duty of entering the compartment and caring for the fixtures between each two uses.
